A4411 21/00 ABSTRACT OF THE DISCLOSURE Cargo tiedown web is adjustably connected with a pivoted takeup lever, which can be locked in the web tensioning position by a manually releasable catch, and duplicate terminal hooks pivotally engageable in buckle frame or connected with Web.

FIG. 1 is an edge View of one of the cargo tiedowns embodying the invention, in the closed, web adjusted and tensioning position.

FIG. 2 is a plan view of the same.

FIG. 3 is a broken sectional view on substantially the plane of line 33 of FIG. 2.

FIG. 4 is an edge view of another form of the invention and FIG. 5 is a plan view of the same.

FIG. 5a is a broken perspective view of a hook formation.

FIG. 6 is a plan view of a further, modified 'form of the invention and FIG. 7 is an edge view of the same.

FIG. 8 is an end view of the frame.

In the first illustrated form of the invention, FIGS. 1, 2 and 3, the web tensioning buckle structure consists of a U-shaped frame made up of parallel side portions 10 and 11, connected in spaced relation by an end portion 12 and a web tensioning lever consisting of a plate 13, hawing cross slots 14, 15 through which a loop 16 of the web is reeved and which plate has journal extensions or lugs, 17, pivotally engaged in holes 18 punched in the side walls of the frame.

These pivot lugs are set back from the end 19 of the plate, giving the plate necessary leverage for tensioning the web extended about this end of the plate.

Additional leverage may be introduced by mounting a wraparound about this end of the plate, as shown at 20, which provides a rounded bearing edge for the web and which with the lug extensions 21 lining up with the pivot extensions 17, provides additional pivoting support for the web plate.

To secure the web plate in the closed web tensioning position, at latch member is mounted on the web plate, designed to interlock with a keeper on the frame.

This securing member is shown in FIGS. 1, 2 and 3 as a latch lever 22, pivoted on the end of the web plate at 23, having a tooth 24 to enter an Opening 25 in the projection 26 on the end wall 12 of the frame.

This latch lever is shown provided with an upstruck thumb grip 27 for easy engagement or release of the latch.

In this first form of the invention, the frame is shown as having a hook 28 at the open end of the same, provided with log extensions 29, engaged in pivot openings 30 in thesides of the frame.

This hook is shown as having a cross slot 31, so that it may be used for a web end hook, such as that designated 28a.

If desired, this duplicate use hook may have two or 'more cross slots, depending on whether, when used for a web end hook, the web is to be simply looped through a slot and stitched or otherwise fastened, or it is to be adjustably passed through a plurality of such slots.

Constructed as described, such books may be struck out of sheet metal for direct mounting in the frame or for attachment to webs used with the frames.

The second form of the invention, illustrated in FIGS. 4 and 5, resembles the first illustrated form in having a -shape frame made up of parallel side walls 10 and 11, connected by an end Wall 12 and a web plate 13, pivoted in the side walls by integral lug extensions 17, but the web plate has an extended handle portion 32 at the free end, providing desirable leverage for tensioning the web and this extended handle portion has a slot 33 for passage of the upstanding hook 34 on the end wall.

This hook forms a latch for securing the web plate in the tensioning position and the plate is pivoted in the frame with slight free motion sufiicient to permit the plate to snap down into and to free itself from engagement with the hook, on slight side pressure on the extended handle portion of the plate.

In the FIGS. 6 and 7 form of the invention, the closed end 12 of the frame is made with a downward extension 35, rounded off at the bottom at 36, to provide a smooth surface for hearing on cargo and this extension is shown as having a guide passage 37 therethrough, for the web 38, which is shown as having a double run looped through end hooks 39 and 40, with one end caught to the buckle frame and the opposite end adjustably engaged in the cross slots in the web plate 13a.

The invention provides a light, but strong, small size tensioning buckle which can be made up of sheet metal parts at relatively low cost.

The U-shape frame is stiffened and reinforced by the web plates and end hooks engaged in the sides of the frames.

If additional cross bracing is required, the sides may be connected by a cross brace bar, such as shown at 41, FIGS. 4 and 5.

If greater strength or bearing surface is required for the hooks, they may be doubled one on top of another as indicated :at 39 and 40 in FIG. 7.

While the terminal hooks have been shown connected with the buckle frame either by pivoting them to the frame or connecting them with a web, it is contemplated that the terminal hook on the frame may be rigidly connected with the frame or may in fact be formed as an integral part of the frame.

The U-shape frame first illustrated, has the advantage that it may be made up inexpensively out of strip stock bent into the U formation.

This frame, however, may be made up in channel formation or be made up of separate side pieces fastened together in spaced relation by welded or riveted or otherwise secured cross braces.

What is claimed is:

1. A web tensioning cargo tiedown with a manually releasable lock, comprising a U-shaped frame of spaced parallel'side walls connected at one end by an end wall,
